Isolation system: for when you're sick of hearing stuff

If you really, really need to cut external noise out of your life every day, you could buy some noise canceling headphones or move away from the honking horns and sirens of the big city. Alternatively, you could buy a CD of white noise and some sound isolating earphones for an unreasonable amount of money. The earphones are custom fitting, so they block up to 90% of external noise out like a pair of solid earplugs. In addition you can blast some white noise through them via the included CD and really cut yourself off from your surroundings. You won't be able to hear your baby crying or the smoke alarm going off, but boy you'll feel like you're on a vacation from yourself. All this for a mere $315? I'll take ten!
